Do anyone else has this Problem with Movie Blackout?

When i am transforming him back to Vehicle mode the piece of the cockpit there contains the automorph flips up anytime i attach the leg parts under the back. How can i explain it, each time i attach the under part to the upper part of the helicopter the cockpit keeps popping up.
Am i transforming him wrong, or could there be something wrong with my figure? When i bought him he was tight in Helicopter mode.
